I would like to refer to the example of matlab above to create a user who is statically fixed in the middle of the map, not a user who moves along the trajectory.
So I modified it a little bit and wrote the code, and when I run it, the figure comes out well, but there’s an unknown error, so I need some help.

Expected input to be an array with number of columns equal to 3.

^^^^^^^^^^^^^^^^^^^^^^^^^
I’m getting this error, and I’m curious about the solution. I’m also curious if there’s any problem even if I ignore the error and use it.

This question originates from a reply in the following: thread.
I once wrote a python script that would try to get a floating license every 10 secs. From that idea now I thought maybe I can do similar one that would identify if MATLAB is idle more than 5 minutes or so, and then it would terminate the MATLAB.
Would this be a license violation, or is it just strictly altering the Network License Manager to timeout in less than 4 hours?This question originates from a reply in the following: thread.

I am using the multi-window app facility (documented here) to create a dialog box a little fancier than the ones intrinsically provided. It provides an edit field in which the user may type a file name. I would like to arrange it so that if the user presses Enter after typing the file name, it triggers the Load button. I find that, if the keyboard focus is in the dialog generally, a KeyPressFcn callback for that dialog will be triggered. But if the keyboard focus is in a specific edit field, it won’t. But that is precisely what I want! Is there a way?

Hello everyone. I have this task, does anyone have any ideas on how to do this or ready-made examples of something like this?

System description
Input:
– only one input
– during all time input gets a series of data
– at each cycle input signal is either 0 or 1
– type boolean
Output:
– only one output
– at each cycle time, the system sets the output 0 or 1 that depends on
conditions
– the system sets the output to 1 if the sum of 1 in the last input
series was odd.
– in other cases, the system sets the output to 0
– type boolean
Definition of the series:
Series starts with 2 nd 1 in sequence (1 | 1).
Series ends after 2 nd 0 in sequence (0 0 |).
Example of input data and series:
input 0 1 0 1 | 1 1 1 0 0 |1 0 0 1| 1 1 1 0 1 0 0| 0 0
output 0 0 0 0 | 0 0 0 0 1 |1 1 1 1| 1 1 1 1 1 1 0| 0 0

I am using three subsystems: one contains a Stateflow chart with states, and the other two contain Simulink functions, each with its own Stateflow block. I am using nested Simulink functions and calling them through Stateflow. However, the states are not executing properly inside the Simulink functions. Can anyone help me understand why this is happening and what might be causing it?
I have attached some snapshots and the .slx file for your reference and clarification.I am using three subsystems: one contains a Stateflow chart with states, and the other two contain Simulink functions, each with its own Stateflow block.

ylabel(‘x2’)Dear All,
I’m trying to draw a set of constraints but I got a wrong line for the constraint 2×1<=3 !!!! I need a vertical line !! I approciate any help from you !!!
Many Thanks,
Nadia
